Medium Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.

Hot Water

Fuel Type To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.

Oil

Combustion Type

Conventional

Vent Type Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.

Chimney Vent

DHW Production DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.

Modulating/Staging Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

DOE Heating Capacity Also referred to as Gross Output, this is the output of a boiler after accounting for combustion efficiency. We recommend sizing hot water boilers based on the DOE Heating Capacity.

167000 BTU

Net I=B=R Capacity I=B=R, also referred to as Net Output or AHRI Capacity, is the rated heat output of a boiler after accounting for combustion efficiency, piping loss, and an extra pickup factor. We recommend sizing steam boilers based on the I=B=R rating.

Burnham is devoted to pushing the limits of heating technology and efficiency. Their ingenuity is responsible for some of the most efficient boilers on the market today. The MPO-IQ is a brilliant marriage of reliable design elements and advanced controls. The result is an incredibly efficient boiler that is easy to use. A 3" thick insulated jacket and vacuum-formed burner door provide the MPO-IQ189-LLU with superior heat retention, one of several ways that an MPO-IQ hot water boiler reduces your energy consumption without compromising your comfort. In addition to superior insulation, MPO-IQ boilers also improve efficiency by virtue of their three-pass heat exchanger, which recirculates heat instead of venting it away. Whether you are replacing an existing oil boiler or this is your first, the MPO-IQ is a fantastic choice.

Product Features

Intelligent Oil Boiler ControlAll MPO-IQ boilers have Burnham's IQ Control System. The IQ system consists of two primary components: an IQ Option Panel and an Intelligent Oil Boiler Control. The Intelligent Oil Boiler Control is the centerpiece of Burnham's IQ Control System. It has an adjustable setpoint, provides two relays, and acts as an aquastat.

IQ Option PanelThe IQ Option Panel provides a standardized and simplified way to add functionality to your boiler. It supports Burnham's IQ Option Cards for outdoor reset, an auxiliary high limit, and low water cutoff. Options card are plug-and-play, which means customizing your MPO-IQ189-LLU is easier than ever.

Superior AccessibilityThe MPO-IQ189-LLU is designed for ease of installation and maintenance. The burner door is reversible and the rear plates may be removed easily for access to the flue passages.

Simple VentingMPO-IQ boilers include a barometric draft regulator and stainless steel flue baffles. These components provide simple, safe, and efficient natural draft venting for your boiler. With the installation of a Beckett NX burner, you may use the MPO-IQ189-LLU in direct vent applications.

Durable ConstructionThe incredible longevity of MPO-IQ hot water boilers is owed, in part, to the proprietary BC25HSi silicon-inoculated iron used for the boiler sections. Additionally, the heat exchanger is made from cast-iron, which allows it to accept lower return water temperatures. By using a lower system temperature when possible, you will save energy and prevent short-cycling.
